Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x
Answer: x = -7
Step-by-step explanation:
7 (x + 4) = -21
7x + 28 = -21
Subtract 28 from both sides
7x = -49
Divide both sides by 7
x = -7
Answer:
Wednesday
Step-by-step explanation:
A 18 sessions and we know that a session lasts 7 days. We also know that the sessions are grouped and that there is only a break after every 2 sessions. The sessions can only be held on weekdays which is 5 days. The first session starts on Friday. We need to determine the last day of the 18 sessions.
WE can assume that a break is a one day.
The first two sessions will be a total of 14 days and then a break. Friday adding 14 days will result in the first two sessions ending on Wednesday and a break day. The next two sessions will start Friday again.
Therefore the sessions are even number of 18 and therefore will always end on a Wednesday
